What is a vascular graft?
Vascular graft is a tube in the shape of synthetic material surgically implanted into veins and arteries. The diameter and length of the graft will vary depending on the replacement of the size of the artery or vein. These grafts are used for peripheral vascular bypass operations and for creating access to veins in patients with hemodialysis. Vascular grafts can be made of several different biocompatible materials.
One type of vascular graft is made of natural collagen. Collagen fibers are woven together to create a very flexible small tube. To create an arteriovenous (AV) portal used for hemodialysis is most often used grafts based on collagen. Vascular grafts AV connect the vein and artery together to create a stable opening for dialysis treatment. This unique graft is often implanted to create an access point AV dialysis. After removing the dialysis needle, the graft seal was closed, resulting in blood leakage into the surrounding tissue. One of them is the graft made ofmaterial covered with anticoagulant heparin. The use of anticoagulance to the graft surface can reduce the risk of thrombosis, clots in the blood vessel, causing graft failure. Another graft material includes a carbon -based substance that can reduce the likelihood of blood clots. These grafts are often used in cardiovascular operations.
After surgery to implant vascular grafts, the patient will be carefully monitored for potential complications. Plates can be abnormally clustered on the surface of graft, bmed to circulate blood and extend the amount of time required to heal the graft site.
may cause bacterial infection and slow the healing process. Some people with bacterial infections from graft become septic and shock. It is possible that Štěp fails, which requires surgery to remove and replace graft.
OCCLUSION or BLOCKTAGE, graft is a serious complication of POStupu. People who smoke or have high blood cholesterol have a high risk of graft occlusion. Diabetics are more likely to have poor blood circulation, which may be a contributing factor to a higher level of graft failure in diabetic patients. Medicines against dealet and anticoagulant drugs may be prescribed to prevent blood clots to block the passage of blood by implanted graft.
measures can be taken to prevent bacterial infection of vascular graft. The daily application of new sterile bandages and bandages can prevent the infection of the graft site. Antibiotics can be prescribed during the period of critical healing after surgery. Good nutrition, lots of fluids, and beneficial sleep could help some people avoid disease after surgery of vascular graft.
